IMPROVEMENT lN SEATS FCR HARVESTERS.

Specification forming part of Letters Patent No. 137,816, dated Aprill5, 1873 application led September 23, 1872.

To all whom it may concern:

Be it known that I, GEORGE W. N. Yosr, of Corry, Pennsylvania, haveinvented an Improved Mowing and Reaping Machine, which I call the Acme,of which the following is a specification:

The nature of that part of the invention included in this division, andto which the application for a patent therefor is conned,

` when the seat is let down low. Fig. represents a view of one form ofchangeable rests for the supporting-arms, and Fig. represents aview ofanother form of changeable rests for the supporting-arms. Fig. 7represents a view of a foot-rest detached from the seat.

The following is the description: A represents a main axle of a mowingor reaping machine. B represents a driving-wheel on each end of the mainaxle A. C represents an inclosing-box main frame hinged on the main axleA between the driving-wheels B. D represents a hinge-lug, a part of orrigidly attached to each side of the main frame C, and extendedlaterally parallel with the main axle A. E represents an arm, hinged oneach hinge-lug D of the main frame C, and extended nearly horizontallyat a rightangle to the main axle A. F represents a seatspring on eachsupporting-arm E, and extended upwardly. Grepresents aring or loopattached to the lower end of each seat-spring F, and over the contiguoussupporting-arm E, and adapted to be moved to and from on the arm forconvenience. I make this ring in the form of a staple, and put it upastride or over the arm and through holes in the seat-spring. Hrepresents a screw-nut on each end of each staple G of each seat-springF, by which the seat-spring is screwed fast to its supporting-arm E. Irepresents a cam pivoted to each side of the main frame O y under asupportingarm, E, as a rest for the arm to lie on. J represents ascrew-pivot through each cam I, and. screwed into the main frame G. Krepresents a seat for the operator, attached to the upper ends of thesprings F. L represents a foot-rest rigidly fastened to the bottom ofeach seat-spring F, over a supporting-arm, E, by the loop or staple Gand screw-nuts H. j

The cam I may be a wheel, as in Figs. 1, 2, 3, 4, and6 5 or it may be amany-sided ring, as in Fig. 5, or in any other suitable form.

If the cam I is a wheel the pivot J is put through the cam out of thecenter nea-rer one edge, as in Figs. l, 2, 3, 4, and 6, and, if amany-sided ring, the pivot is put through one corner, and equally out ofthe center, as in Fig. 5, so that in either case when the cam revolveson its pivot its circumference will move in an eccentric line. This willenable the seat K on the supporting-arm E, which rests on the cams I, tobe raised or lowered, as in Figs. 3 and 4, which makes the seatadjustable in an upward and downward direction.

By loosening the screw-nuts H, the seat K, with the rings or loops G,can be moved to andfrom lengthwise on the supportingarms E, which makesthe seat adjustable in a forward and backward direction. The footrestsL, being attached to the seat-"sprin gs F, will move up or down orforward or backward as the seat is moved, being adjustable in the sameway that the seat is adjustable. Thus the seat is doubly adjustable, canbe moved lengthwise, according to the weight of the operator, so as tobalance the cutting apparatus, or up or down, according as the inachineis reaping or mowing.

I make a groove in the edges of the cams I 2.
